The Apple Macintosh Plus was first released in 1986 which means that getting your hands on a brand new one today is either impossible or going to be very, very expensive. But what if you really want one and don't want to spend the kinds of sums a new, boxed original would likely cost? Well, you make yourself one.That's what Kevin Noki did when he bought a Macintosh Plus from eBay. The problem? It had a broken power supply and floppy drive which just wouldn't do, so he set about creating the Brewintosh. It's like a…

MIT researchers modified a multi-material 3D printer so it could produce three-dimensional solenoids in one step by layering ultrathin coils of three different materials. It prints a U.S. quarter-sized solenoid as a spiral by layering material around the soft magnetic core, with thicker conductive layers separated by thin insulating layers.

3D printing has made some massive strides. In fact, in recent years, we’ve even started to see architects experimenting with using 3D printing to create entire houses. If you really want to be astounded, though, you should check out the video below, which showcases how Europe’s biggest 3D-printed building was printed in just 140 hours.That’s an astoundingly short amount of time for an entire building to be erected, and The Wave House, a data center located in Heidelberg, is what many consider a significant…

A new type of 3D-printed lattice structure has surprised researchers with its strength and light weight. It uses two different lattice structures merged together to eliminate the weak points normally found in these complex shapes.RMIT researchers in Melbourne, Australia, took hollow-strut lattice designs as a starting point, inspired by hollow-stemmed water lilies and organ pipe coral, and then looked at ways to reduce the high stress concentrations created at the join points.“Ideally, the stress in all complex cellular…

Is it a flying elephant? A gingerbread man? When I was little, I used to search the clouds for amusing shapes as they drifted across the sky and imagine stories about their patterns. Now I'm a professional stargazer, and things haven't changed much. These days I search for patterns in molecular clouds, the birthplaces of stars. The shapes I find in these stellar nurseries do more than stimulate my imagination—they also tell a very real story about when, where and how stars are born. For astronomers, understanding this…

Researchers at TU Wien have developed a new way to grow cartilage from stem cells and guide it into basically any shape required. The breakthrough could lead to better ways to patch up injuries.Cartilage is the rubbery tissue in joints that acts like a cushion to stop bones rubbing against each other. But as important as it is, it has almost no regenerative ability in adults, so when it’s damaged due to injury or just decades of wear-and-tear, it can lead to painful chronic conditions like osteoarthritis.Scientists are…

If you're the proud new owner of an Apple Vision Pro you have no shortage of accessories to choose from. Quite apart from all the different components that make up the Apple Vision Pro box's contents, Apple will sell you a wide variety of different bits and pieces that can be used with the headset. And some of them are definitely priced to match the $3,499 starting price of Apple's first foray into the world of spatial computing.Those accessories include an additional Apple Vision Pro battery pack for a cool  $199, while…

Cocuus, a cutting-edge tech startup headquartered in an industrial estate on the outskirts of Pamplona, embraces the cliches of its sector every bit as willingly as the drunken tourists who blithely entrust themselves to fate, horns and hooves during the Spanish city’s bull-running festival each July.Table football? Check. Lager and IPA on tap? Check. Inspirational messaging – preferably an Alice in Wonderland homage that reads, “I believe in six impossible things before breakfast”? Check. What about some sci-fi…

A group of researchers working with the University of Wisconsin-Madison claim to have created the first 3D-printed human brain tissue that is actually functional. The group says it hopes that their research will open new doors for studying existing neurological disorders like Alzheimer’s.The researchers published their findings in a paper featured in Cell Stem Cell, detailing how they created the 3D-printed brain tissue using horizontal layers of “bio-ink” gel.“The tissue still has enough structure to hold…

Researchers have created the first functional 3D-printed brain tissue that can develop and form connections in the same way as real human brain tissue.This remarkable accomplishment by a team at the University of Wisconsin–Madison provides neuroscientists with a new tool for studying communication between brain cells and other parts of the human brain, potentially leading to better ways of treating diseases like Alzheimer's and Parkinson's."It could change the way we look at stem cell biology, neuroscience, and the…
